Working with monitors
Expand all | Collapse all
Monitor management is available to system administrators.
In the Event Processor → Monitoring section, you can create monitors for monitoring specific events, patterns, or values of event parameters.
The Monitoring tab displays all monitors created in the application, including the following brief information:
- Monitor name.
- Monitor threshold.
When this number of monitor activations (threshold) on the sliding window is reached, the application sends an alert about monitor activation to the external system.
- Sliding window used to track the number of monitor activations.
- Number of monitor activations on the sliding window.
If necessary, you can view detailed information about each monitor by clicking the Information button located next to the name of the relevant monitor in the table.
- Monitor ID is the unique identifier of the monitor being viewed.
- Number of activations on the sliding window refers to the number of registered monitor activations on the sliding window.
- Date and time of last activation refers to the date and time when the monitor was last activated.
- Activated refers to the type of element that caused the monitor activation. Monitor activation may be invoked by a new or existing event parameter value, event, pattern, or another monitor.
- Subscription indicates what is being tracked by the viewed monitor: event parameter values, events, or patterns.
- Sliding window indicates the time interval from the current time back to the time sequence for which the number of activations is taken into account. This window shifts synchronously with the passage of time according to the timestamps in events.
- Threshold indicates the number of activations to be registered by the monitor on the sliding window before sending an alert about the monitor activation to the external system via the CEF Connector.
- Filters is a table containing information about filters for event parameters observed by the current monitor to track event parameter values, events, and patterns. The following data is displayed for each element:
- Parameter name refers to the names of event parameters whose values are being observed by the viewed monitor.
Each monitored asset has its own specific incoming events and event parameters. The names of event parameters are defined in the configuration file for the Event Processor service. The configuration file is created and uploaded by a qualified technical specialist of the Customer, a Kaspersky employee, or a certified integrator during configuration of the Event Processor service.
- Type defines which types of values are being tracked by the monitor: specific values, new values, or all values.
- Purpose defines which event parameters are receiving focused attention from the model.
- Values refers to the values of event parameters that are being observed by the viewed monitor.
- Stack limit determines the number of most recent monitor activations displayed in the Activation stack table.
- Activation stack is a table that contains information about the latest activations of the monitor:
- Parameter value ID is the ID of the event parameter value whose detection caused the monitor activation. This parameter is displayed only when the monitor is activated by an event parameter value.
- Event ID is the ID of the event whose detection caused the monitor activation. This parameter is displayed only when the monitor is activated by an event.
- Pattern ID is the ID of the pattern whose detection caused the monitor activation. This parameter is displayed only when the monitor is activated by a pattern.
- System parameters is a group of system settings containing the following information:
- Event time is the date and time when the event is detected in the event stream.
- Interval from previous item is the time interval between the current and the previous event in the event stream on the sliding window. Kaspersky MLAD displays the time intervals between events upon the first detection of the pattern containing the events. When a pattern is detected again, the Event Processor takes into account the coefficient of allowed intervals dispersion specified by the administrator for these events.
- Total activations is the number of event occurrences in the event stream on the sliding window.
- Parameter count is the number of event parameters for which the values were received from the monitored asset.
- Last activation is the date and time when the event was last detected in the event stream on the sliding window.
This group of parameters is displayed only when the monitor is activated by an event or an event parameter value.
- Activation date and time is the date and time when the monitor was activated. This parameter is displayed only when the monitor is activated by a pattern.
- Event parameter is the value of the event parameter received from the monitored asset. This parameter is displayed only when the monitor is activated by an event parameter value.
- Event parameters are the values of the parameters of the event received from the monitored asset. This parameter is displayed only when the monitor is activated by an event.
- Events is the number of events included in the pattern that caused the monitor activation. This parameter is displayed only when the monitor is activated by a pattern.
You can view information about the events included in the pattern by clicking the number of events in the corresponding row of the table. Clicking the number of events displays information about IDs, system settings, and parameters of the event included in the selected pattern.
On the Histogram tab, you can also view brief statistics on the number of registered activations for each created monitor.

Creating a monitor
Monitor management is available to system administrators.
To create a monitor:
- In the main menu, select the Event Processor → Monitoring section.
- Click the Create monitor button.
The Create monitor pane appears on the right.
- Specify the monitor name in the Name field.
- In the Sliding window (sec.) field, specify the interval (in seconds) from the current point in time back to the time sequence for which the monitor will process incoming values of parameters, events or patterns.
- In the Threshold field, specify the number of monitor activations in the sliding window after which the monitor sends an alert to the external system.
- In the Stack limit field, specify the number of monitor activations that must be displayed when viewing information about the monitor.
- In the Subscription type drop-down list, select one of the following values:
- If you need to process data on the values of event parameters, select Parameter values.
- If you need to process data on events, select Events.
- If you need to process data on detected patterns, select Patterns.
- If you need to track new events, patterns, or values of event parameters, turn on the Only new toggle switch in the Filters section.
- To focus the attention of the model on specific directions of events, do one of the following:
- If you selected Events from the Subscription type drop-down list, select Attention for the relevant event parameter. If you need to track events without specifying the attention direction, clear the Attention check box.
- If you selected Patterns from the Subscription type drop-down list, select the Attention check box for the relevant event parameter.
You can select only one attention direction.
- For each event parameter, do one of the following:
- If you need to process data on all values of an event parameter, use the drop-down list to select All parameter values.
This option is displayed if you specified the attention direction for the current event parameter.
- To process data only on the new values of an event parameter, in the drop-down list select New parameter values.
This option is displayed only when the Only new function is enabled for event-based data processing.
- To process data for a specific value of an event parameter, in the drop-down list select the event parameter value. As you start typing a value, all matching parameter values are displayed in the list.
If the parameter value is not listed, enter the required value and select Create Value: <event parameter value>.
- If you need to process data based on an event parameter value template, turn on the Regular expression toggle switch for the relevant event parameter, use the drop-down list to enter the value template with a regular expression, and select Regular expression: <value template>.
You can use special characters of regular expressions to search patterns using regular expressions.
- Click the Create button.
The new monitor is created and displayed on the Monitoring tab.
